how is vmix configured now?
setting vmix1_masterdev=5
in vmix.conf seems to have no effect anymore now.

[edit]
i just found out that the conf/*.conf files act directly as module parameters, so no wonder that it didn't had an effect as the module vmix doesn't exist anymore..
but my logical conclusion that now osscore takes the parameters of vmix was wrong..
so the question stated above remains

I have a Creative X-Fi eXtreme Gamer and I'm wondering where are located osscore.conf and vmix.conf ? I don't have sound anymore with SMPlayer nor VLC (or any video player, but all audio player works) because vmix is missing in /usr/lib/oss/etc/installed_drivers. With the 1015 version and vmix in /usr/lib/oss/etc/installed_drivers sound works well on my Debian. But since it's now in OSS core so I doubt I have to add it, but to configure those *.conf... I guess ?

Edit :Ok sorry i was wrong. I found that I need to select ESD instead of OSS in gconf if I want to enable system sounds, then enable ESD in audio/video players too to get sound, or OSS but without system sound. Does it make any difference ? Does ESD uses OSS driver when it's enable ?

please note, that GNOME is using ESD for its system sounds. Currently there is no other way to enable them without ESD. However, as OSS uses VMIX, ESD will start fine and use one "VMIX PCM" all the time, but it won't harm.

Again, you need to enable ESD in the GNOME options and the "Play system sounds" option in order of being able to hear those system sounds.

Btw, I am not very sure, but I guess this is the wrong thread and forum section for those questions.

In my latest update to oss, the ossxmix now don't show me the softwares using the soundcard.
individual volume works in the application, but ossxmix show nothing.
I have a Turtle Beach Montego (oss_vortex).

While the driver was obsoleted, it's still part of the source tree. Fetch the source, link attic/drv/oss_vortex to kernel/drv/oss_vortex then rebuild & install as usual (see here for instructions on getting the source and building it).
